Migrating Hyper-v to larger drive

[MassiveJim]

I had a pre-fail warning pop-up yesterday on one of my RAID1 drives that host my hyper-v and all of its VMs.

I have 2 larger SSDs being delivered today to replace both drives.
server is an R720 with no free bays (although 1 bay is a hot swap drive which could be used)

My question is what is the most painless way to migrate the hyper-v host and all VMs to the new larger drives ?

I won't be able to pull the failing drive and just resync the RAID array as the old drives are 15k SAS, and the new drives are SATA SSDs.

Put new drives in with old drives, configure new drives how you want them, software raid for example, create volume on hyper v host with new drives, storage migrate VMs to new said storage.

Hyper-V is installed/running from the array that has the failing drive. I not only need to migrate VMs but the host OS as well.

I had to do the same thing recently, I just created an image of the existing array/install to an external source then fitted the new drives and imaged it back.

that is what I ended up doing.

only issue now is I decided it would be better to have the VMs on a seperate partition, Windows cant resize partitions very well.

I pulled one of the RAID drives and used Ease US to do the resizing in another machine, but now that drive was no longer recognised by the RAID controller.
So now going to try imaging the resized drive and rebuilding the array then restore that image to the array, fingers crossed it works, I want to go home now
